Abstract: A method of facilitating the reproduction of a presenter's desktop for attendees of a real-time collaboration. A bound portion of the desktop (the portion shared with the attendees) is logically divided into clusters. When the content of a cluster changes, the cluster is analyzed and one or more objects describing the content may be identified. Each object that is not already cached is cached and assigned a cache ID. Each object in the cluster is described in an object primitive to be sent to the attendees. Actions for reproducing the object on the attendees' clients are sent as action primitives. The object and action primitives allow the content of the presenter's desktop to be sent incrementally instead of sending the entire desktop.

Abstract: A real-time collaboration client and a method of configuring the client for a real-time collaboration with requiring the client to be rebooted. A secondary table of display driver calls is patched to call a redirection table instead, while the primary table is unaltered. Redirected calls are passed to the display driver and to a collaboration module configured to update the collaboration to reflect the display driver call. The video mode of a client video display is then changed, at which time the secondary table is copied over the primary table and made active. If the client is rebooted, a loader module loads before the display driver and intercepts a call to load the display driver. The loader module loads the collaboration module and modifies a return value to the call to cause display driver calls to be directed to the redirection table.
